Customer Testimonials

★★★★
It's noticeable but understated. It doesn't tarnish at all, even when worn every day, and the best part is I don't have to take it off while working out.

I bought this as a gift for my boyfriend. I was surprised by the luxurious feel of the original box. He was incredibly happy with it, and I'm very satisfied.

I have a metal allergy, but since this is surgical stainless steel, there's no rash. I even wear it in the ocean and there's no discoloration, it's the best.
